| 摘 要： | 为了研究两平面相交可见性的规律，从空间一个平面的投影特点入手，将平面分别设定为正面、背面两面，讨论平面图形各顶点投影顺序与平面正面、背面的投影所具有的内在规律。提出并论证了各种位置直线与平面相交，直线在相邻两投影面上可见性的投影规律。同时，阐述两平面相交交线的空间位置情况，从而得出两平面相交可见性判断的新方法。

| Abstract: | To study the intersection visibility of two general place planes, this paper set the planes as two faces of front and backs from the point of projection character of a space plane. The projection sequence of plane graphs apex and relationship of the sequence and plane faces were discussed in this paper. The intersection visibility rule of a line and general plane was concluded and a new judge method on intersection visibility of two general place planes was also put forward in this paper. |
